Last week I got my GNex wet and the apparent results are:

• Glitchy power button (press and long press frequently do not work, regardless of whether the phone is on or off). This may well be caused by mainboard hiccups.
• Volume rocker does not work at all (and I have the version where the rocker ribbon is soldered on to the mainboard).
• Screen auto-off does not work properly.
• Screen displays scanline effects and a single row of green pixels at the bottom.
• GPS does not work (as in will not run at all - enabling it does not launch the background service notification about the fix state.)

Calling, receiving calls, and sending and receiving SMS works fine. 3G works fine. Wireless works fine. Having the screen almost always on is totally unacceptable.

It was on at the time of the water event. I pulled the battery, let the phone dry properly, then disassembled and cleaned with alcohol any parts showing corrosion. Warranty is not a thing.

I'm contemplating:

1. Buying parts (screen ~ 150US, power button ~ 3US) and replacing them myself. I'm not sure if I can get a new GPS and mainboard so I'd be risking living with a broken volume rocker and GPS / sending it to Samsung to get those replaced anyway.
2. Sending it to Samsung to get it fixed. Not sure about the cost involved.
3. Buying a new phone. I like being on Google's update path, so I'm contemplating the Nexus 4, the One, and the S4.

I would almost certainly buy a Nexus 4 straight from Google (300US for the 8GB, 350US for the 16GB) and get it via NZ Post's YouShop remailing service if I knew a way to get around Google's payment restrictions.

Any suggestions/recommendations? (Whether to buy or repair, and if buying then advice re. device of choice would be appreciated.)
